'Ilfoob UNITED STATES JOHN MATTHEWS, OF NEW YORK, N. Y.

IMPROVEMENT IN SODA-WATER FOUNTAINS.

Specification forming part of Letters Patent No. 128,411, dated June 25,1872; antedated June 13, 1872.

To all 'whom it may concern: Y

Be it known that I, JOHN MATTHEWS, of the city, county, and State of NewYork, have l invented a new and Improved Fountain for fountain combininglightness with strength,

and being of cylindrical form and uniform dimensions, or thereabout,throughout its length, thereby adding to the convenience of packing andhandling 5 also being exempt from expansion or permanent lateraldistention by the interior pressure to which it is subjected, thuspreserving its form and contributing to its durability. Fountains forthe like purpose, as previously made, have beenlargely expansive, andretained the set given to them by extension, and being otherwiseobjectionable.

In the accompanying drawing, A represents a block-tin interior body ofcylindrical form, with hemispherical or reduced ends, the sameconstituting the tin lining of the fountain, and being provided at oneof its ends with a neck, b, for introduction lof the usual or anysuitable connections, by which the fountain is charged and its contentsdrawn oif, said neck receiving or having screwed into it ascrew-coupling, c, secured by a nut and washer, d c, on the exterior ofan outer end cap, B, for making the connection. C is the exterior shellor body proper,made of galvanized sheet-steel, as may also be the endcaps B B', which are soldered to or over the extremities of the same,and constitute, as it were, parts of said body C that closely surroundsor iits over the tin lining A. The end caps B B are united to the body Gwithout anges or projections by tin joints, as at ff, made by solderingwith pure tin, which, being a ringing metal, unites closely with thesteel exterior to make a iirm and durable joint, as other sold'ershaving lead in them will not do. Bands g g of brown paper or othernonconducting material are introduced between the-tin lining A and steelbody O at the ends of the latter to prevent the tin of the lining frombeing melted by the heat used in making the pure tin joints ff. Thefountain is also filled with water for the same purpose prior to makingsaid joints.

The non-stretching character of the body C, by reason of the same beingof steel, insures the fountain preserving its shape, and the absence ofend iianges provides for the close packing of a series of suchformations when transporting or storing them.

What is here claimed, and desired to be se cured by Letters Patent, is-

The tin vessel A incased by a steel cylinder, C, and ends B B solderedto the latter, in the -manner substantially as described, as a new andimproved article of manufacture, for the purpose specified.

JOHN MATTHEWS.
